GC7890 fully automatic computer anti-control gas chromatograph

Bringing together today's mainstream IP communication technology, using the latest high-integration industrial chip, bus technology, Ethernet technology, micro-flow gas control technology manufactured.
This machine completely eliminated the discontinued chip and the soon-to-be-phased RS232 communication port, replaced by the technologically advanced 10/100 adaptive Ethernet communication interface, the host built-in IP protocol line, so that the instrument can easily through the internal local area network, the Internet to achieve long-distance data transmission, Thus completely break the domestic chromatograph's heavy work mode in the past (1 chromatography , 1 AD converter , 1 computer and 1 printer), so that 1 computer operates multiple gas chromatographs (up to 5000 units), and completeall data analysis, printing, storage become a reality; Real-time observation, operation of chromatography instrument online analysis, easy remote control, real-time monitoring.

Perfect, reliable and powerful control system

The instrument is equipped with a monochrome 192 x 64 LCD screen or 5.7 inch color LCD screen, with the Chinese and English interchange display interface;
This machine has a completely independent six-way temperature control system, and can be assembled and replaced at any time set;
Take a powerful multi-CPU parallel processing mode, the reliability of the instrument and anti-jamming performance is superior;
All the parameters on the instrument such as (temperature, event, cheng sheng, etc.) can be set and communicated in both directions through the counter-control workstation, and can freely set their favorite, habitual memory name in order to operate, tailor-made, ending the parameter name fixed by the manufacturer set, rigid definition of history;
This machine has 4 external event functions, support multi-valve switching, etc., to achieve multi-dimensional chromatography system application;
With the 10/100 adaptive Ethernet IEEE802.3 communication interface, the RS232 communication port is eliminated.
Transmission speed, reliability is strong;
Instruments can be docked with automated liquid samplers from multiple manufacturers, such as The AOC-20i of Sajima, Italy
Li HTA's HT series, etc., and realize the counter-control workstation for data processing and hardware control.




New highly stable detectors

A wide range of multi-detector structures, FID, TCD, ECD, FPD, NPD and high-sensitivity TCD, methane conversion furnace, etc., can be installed in a machine can be up to three detectors.
FID collection system, the use of new quartz nozzle, with lower detection limit, stable and durable, polarized voltage rheumator using stainless steel connector, so that high temperature conditions will not be burned, long-lasting and reliable;
FID uses intelligent hydrogen, air automatic control technology, the solenoid valve to achieve automatic gas shutdown, so as to achieve a true sense of automatic ignition function (optional);
FID amplification system using low noise, high resolution 24-bit AD circuit, precision thin-film vacuum resistance elements, specially treated built-in desiccant, so that long-term use will also have a stable output signal;
TCD adopts the latest right-angle installation process, pool body and connector integrated design, making disassembly is very easy, convenient for user maintenance;
In order to facilitate customer demand, the instrument is equipped with TCD dual channel, a chromatography can be installed at the same time 2 sets of TCD detector, to achieve a multi-purpose machine.
TCD is using high resistance value tantalum filament, temperature coefficient of plusmn;0.1 degrees C, and provides 2, 4, 8 x x amplification circuit to meet the requirements of high sensitivity analysis, the unique cavity structure makes the stability of a better.
